If you spend a night at any spot en route, you'll have roughly 24 hours to explore, unless you're heading back in the direction you came. Drivers from all canyon hotels pick up guests from the train station; if you don't have a reservation, ask a driver about room availability. Standard accommodations in the canyon are getting more expensive, especially in El Divisadero and Cerocahui. In high season, I wouldn't arrive at either place without reservations. Rates for hotels in both of these towns usually include meals. The number of rooms is limited, and with groups of 40 or 50 people going through the Sierra, a hotel can be empty one day and full the next. When hotels are full, you'll notice a decline in service in the dining room, or you'll have to wait in line at the buffet even if you're not part of the group. Overbooking rooms also seems to be a problem with some of the large hotels, though it's not common enough that you should worry about it. In Creel, you find the greatest variety of accommodations and restaurants. This is where most of the economical hotels are.
